For a food eating contest (pies), instead of rolling to see who got it done faster try to go with this method:
Detailed steps:
1. Judge characters size and tell them what die to roll based on realistic bite size. (Nolthrir could roll a 4, for example, and Ynnwn
2. Set up pies (a 10 or 20 finishes a pie).
3. have players line up in front of a bunch of pies.
4. Say "GO!". All players roll ONCE. Let players tally their own numbers.
5. Players must wait until the judge says "Bite!" or something before making their next roll.
6. When a player gets to 10 (or 20), they pick up the pie in front of them, and wait for the next roll to start on the next.
7. First person to finish all their pies wins!
8. They win more pie.
An alternative would be to see who can eat the most pie in a set number of rolls.
As for clean up duty... make sure you have people set to stand in front of the furnace to burn 'garbage'.
